Off campus vs on campus

I got into sbu CS major ! I am an international student and have to take a loan for the cost of attendance.... though the tuition fee is comparatively lower, the living cost is damn high ! I would love to know more about off campus and on campus....how is the cost different? And the living style too ! How is the social life their...and not to forget the peaceful environment I need for studying....thanks a lot . I am excited.
